With a resolution four times greater than the more conventional 1920 x 1080 Full HD TVs, the detail and realism is outstanding. Although 4K video is rare at the moment, these fantastic Ultra HD sets come with 4K upscaling built-in, meaning you can get much of the benefit of 4K resolution with standard HD video. This cinematic authenticity aspect of 4K Ultra HD should instantly make the format irresistible to serious film and sports fans. The seemingly enhanced depth within the picture, a result of the vastly increased number of pixels, even makes many viewers feel like 4K Ultra HD images are 3D, even when they're not! The combination of Samsung's 3D Hyper Real Engine, Mega Contrast Ratio, Micro Dimming, and 1000Hz Motion Plus technology all work in harmony to produce pictures full of vibrant colours, deep blacks, and crisp sharp images. The picture quality really is astonishing. Internet access is a vital extra for many with a new TV, and with the all new, better than ever Samsung S.
